Summary:                    BYE to 408 Request Timeout
Description: 
Noticed * is generating BYE request to "408 Request Timeout" response.
I don't think this is correct, as 4xx,5xx and 6xx responses to INVITE
should
be only acknowledged with ACK (RFC3261 - 13.2.2.3).

Proxy                                 Asterisk
|<-----------------------(sdp) INVITE F8<|
|>F9 100 Giving a try ------------------>|
|>F13 408 Request Timeout -------------->|
|<------------------------------ ACK F14<|
|<------------------------------ BYE F15<|  <= THIS SHOULD NOT BE HERE
|>F18 404 Not here --------------------->|

Please see 408-flow.html attached for detailed call flow.

How to reproduce:
1. You will need a SIP proxy (eg. OpenSER)
2. Edit sip.conf attached and modify <ASTERISK_IP>, <PROXY_IP>,
<DEAD_HOST>
3. Start * with sip.conf and extensions.conf attached.
4. Dial into * with any SIP phone

    Only send a BYE when hanging up a channel that is up.

    For cases where Asterisk sends an INVITE and receives a non 2XX final
    response, Asterisk would follow the INVITE transaction by immediately
    sending a BYE, which was unnecessary.
